Rivers of Tasmania are the network of perennial and seasonal waterways draining the island state of Tasmania in Australia. They originate in ranges such as the Central Highlands (Tasmania), flow through landscapes including the Western Tiers, Tasman Peninsula, and the Derwent Valley, and discharge into bodies like the Tasman Sea, Bass Strait, and Southern Ocean. These waterways have shaped the island's Aboriginal Tasmanian heritage, colonial development in places such as Hobart and Launceston, and modern industries like Hydro-Electric Commission projects and Hydropower generation.
Tasmania's rivers arise from orographic rainfall over ranges such as the Tasmanian Wilderness World Heritage Area, the Cradle Mountain-Lake St Clair National Park, and the Ben Lomond plateau, feeding catchments like the Derwent, Tamar, and Gordon. The island's maritime climate influenced by the Roaring Forties produces high runoff in the west and south-west, while the north-east exhibits lower precipitation near Bicheno and St Helens. River morphology ranges from braided channels on the Furneaux Group margins to deeply incised gorges such as the Gordon River Gorge and estuarine systems at Hobart and Beauty Point. Hydrological regimes are modified by impoundments like the Lake Pedder system and Lake Gordon, and monitored by agencies including the Bureau of Meteorology and the Department of Primary Industries, Parks, Water and Environment.
Major catchments include the Derwent draining Hobart, the Tamar system at Launceston, the South Esk River and Macquarie in the north, the Gordon and Franklin River in the southwest, and coastal systems such as the Cam and Ringarooma River. Other notable waterways include the Huon River, Arthur, King, Mersey, Forth, Leven, Meredith River, Styx, and smaller estuaries like the Coal River. Drainage divides link to landmarks such as Mount Field National Park, Mt Wellington, and the Western Tasmania Aboriginal Cultural Landscape.
Tasmanian rivers support endemic fauna including the Tasmanian devils' habitats near riparian zones, the threatened green and gold frog in upland streams, and fish like the native Australian bass alongside diadromous species such as short-finned eel and galaxias. Riparian vegetation comprises species of the Eucalyptus complex in lowland floodplains, cool temperate rainforest in the Gordon-Franklin catchment, and heathland near Bruny Island. Riverine ecosystems provide refugia for endemic invertebrates described in studies by institutions including the University of Tasmania and the Tasmanian Museum and Art Gallery, and host migratory birds recorded by the BirdLife Australia network at wetlands like Sea Elephant Bay and Little Swanport. Aquatic ecology is influenced by water quality parameters monitored under frameworks tied to the Environment Protection and Biodiversity Conservation Act 1999.
Rivers have been harnessed for water supply to urban centres such as Hobart and Launceston, for irrigation in regions like the Northern Midlands, and for hydroelectric generation through schemes developed by the Hydro-Electric Commission and its successors. Management involves stakeholders including the Tasmanian Aboriginal Centre, local councils like the Glamorgan–Spring Bay Council and Derwent Valley Council, utility providers such as TasWater, and conservation groups like the Wilderness Society and Tasmanian Land Conservancy. Regulatory instruments reference Commonwealth and state frameworks such as the Water Resources Act 1997 and interaction with federal agencies like the Australian Government's environmental departments.
Rivers have deep cultural connections to Aboriginal nations including the Palawa people, with songlines, shell middens and campsites recorded along the Derwent and Sorell Creek systems. European explorers such as Abel Tasman and later colonists established settlements near river mouths at Hobart, Launceston, and George Town, leading to industries such as whaling, shipping tied to the Bass Strait trade, and mining around the West Coast which used rivers for transport. Controversial events include the Franklin River dam proposals that mobilised activists like Bob Brown and organisations such as the Tasmanian Wilderness Society, contributing to landmark legal outcomes interpreted alongside the High Court of Australia and national debates on wilderness protection.
Pressures on rivers include historic mining contamination from sites like Zeehan and Zeehan-Strahan catchments, hydroelectric impoundment impacts exemplified by the flooding of Lake Pedder, agricultural runoff in the Coal River catchment, and invasive species such as trout affecting native fish. Conservation responses involve campaigns by the Wilderness Society, legal protections within the Tasmanian Wilderness World Heritage Area, and scientific monitoring from bodies like the CSIRO and the Institute for Marine and Antarctic Studies. Restoration projects focus on riparian replanting coordinated with councils and NGOs, and policy work intersects with instruments such as the Environment Protection and Biodiversity Conservation Act 1999.
River corridors provide venues for activities in destinations like Cradle Mountain, Strahan on the Gordon River, whitewater rafting on the Nive River, angling for brown trout and Australian grayling in regions around St Helens and the Derwent, and eco-cruises highlighting wilderness values at Macquarie Harbour. Tourism operators, including those based in Hobart and Queenstown, promote paddling, birdwatching with groups linked to BirdLife Australia, and cultural tours led in partnership with the Tasmanian Aboriginal Centre.
